Townsend's x Hermit Warbler (hybrid)

adult male seen & studied well; facial pattern suggested BT Green because of brighter yellow face and narrow supercilium but had some dark on crown, the back was more grayish than green, and it had extensive yellow on chest. Also, no hint of yellow by base of legs. Thus, superficially the face seemed most like a BT Green but most characteristics suggested Townsend's. The grayish back is the main thing pointing towards Hermit as the other hybrid partner.
